The project involves working within the Spectroscopy and Photometry of Exoplanet AtmopsheresResearch Network (SPEARNET). SPEARNET is a new Manchester-led international survey, involvingcolleagues at Manchester, Open University, NARIT (Thailand) and ARIES (India). It is using a globallydistributed network of optical and IR telescopes, from 0.5m to 8m aperture, to undertake multiepoch,multi-wavelength observations of exoplanet transits. The multiwavelength observations areused to measure the transmission spectrum of the atmospheres of Hot Jupiters and Neptunes. Thegoal of SPEARNET is to provide a testbed for how to conduct optimal, objectively-selected statisticalstudies of exoplanet atmospheres in an era where, thanks to missions such as NASA TESS, ESA PLATOand ESA ARIEL, we expect to have far more targets than we are able to follow up from the ground.
